Decoherence-induced continuous pointer states.
We investigate the reduced dynamics in the Markovian approximation of an infinite quantum spin system linearly coupled to a phonon field at positive temperature. The achieved diagonalization leads to a selection of the continuous family of pointer states corresponding to a configuration space of the one-dimensional Ising model. Such a family provides a mathematical description of an apparatus w...
متن کاملDecoherence of quantum fields: Pointer states and predictability.
We study environmentally induced decoherence of an electromagnetic eld in a homogeneous, linear, dielectric medium. We derive an independent oscillator model for such an environment, which is su ciently realistic to encompass essentially all of linear physical optics. Applying the \predictability sieve" to the quantum eld, and introducing the concept of a \quantum halo", we recover the familiar...
متن کاملDecoherence and pointer states in small antiferromagnets: A benchmark test
We study the decoherence process of a four spin-1/2 antiferromagnet that is coupled to an environment of spin-1/2 particles. The preferred basis of the antiferromagnet is discussed in two limiting cases and we identify two exact pointer states. Decoherence near the two limits is examined whereby entropy is used to quantify the robustness of states against environmental coupling. We find that cl...
متن کاملDecoherence, pointer engineering, and quantum state protection.
We present a proposal for protecting states against decoherence, based on the engineering of pointer states. We apply this procedure to the vibrational motion of a trapped ion, and show how to protect qubits, squeezed states, approximate phase eigenstates, and superpositions of coherent states.
متن کاملExact decoherence to pointer states in free open quantum systems is universal.
In this Letter it is shown that exact decoherence to minimal uncertainty Gaussian pointer states is generic for free quantum particles coupled to a heat bath. More specifically, the Letter is concerned with damped free particles linearly coupled under product initial conditions to a heat bath at arbitrary temperature, with arbitrary coupling strength and spectral densities covering the Ohmic, s...
